上电后,在BRAKE信号无效,且保护逻辑无输出的情况下? 电机按DIRECTION信号的方向转动? 电流传感放大器采样电机电枢电流,经13脚的RC网络转换为电压值,与D/A转换输出的预定阀值相比较。如果当前的电流使转换的电压值小于阀值?(Power after the BRAKE signal is invalid, and the protection logic no circumstances ? electrical output signals according to the direction of rotation DIRECTION ? current sensing amplifiers motor armature current sample by 13 feet of RC network is converted to voltage value, and D/A conversion output compared to the target threshold. If the current of current to voltage conversion value is less than threshold ?)

该文件是学习matlab的国外经典教材，在国内也没有电子书，本人从国外所得(This book is written for the matlab primers of engineering by University of Cabriage.It s easy to learn and grasp.)
